What are the things we need to know about "Hart of Dixie" as it slates its fourth season? Many believe this could be the last for the Rachel Bilson show, for the actress is currently pregnant. Is there a new Zoe to come?

"Thank you, Wade Kinsella, for these four wonderful years. It's been a mighty pleasure knowing you. #picturewrap #HartofDixie," Wilson Bethel tweeted. He, however, gave fans the saddened emotions as this might be the declaration for the conclusion of said series.

The CW network has renewed the series for its fourth installment; in which we are currently sure that it comes back sometime next year. Speculations say it might be January or February.

The highly anticipated show's ratings is currently falling as every season concludes. From 1.77 million viewers in Season 1 (which aired from 2011 to 2012), it fell to 1.37 million viewers on the Season 3 finale. Hence, it could also be relevant for the series concluding all on Season 4.

"That's a wrap on #RachelBilson!  Got thru her last scene without going into labor.  And in 100 degree heat.  Whatta trooper! #HartofDixie," Josh Schwartz, the show's executive producer, said on Twitter. This statement could be another evidence that "Hart of Dixie" might end, unless they are planning to have another Zoe Hart coming. Despite the news are currently limited as of today, fans will continue to hope that it continues.

Reports reveal that several cast members have filmed their last scenes. However, the series has not premiered yet, so there are still chances.

Do you think "Hart of Dixie" Season 4 will be the end for the series? If not, will a new Zoe enter? Who do you suggest? The premiere date for the fourth season has not been confirmed, but it will probably be next year together with the comeback of other The CW shows.
